Point charges of q1= 4.00 and q2=2.00 are placed 0.5 m apart. where can a third charge be placed so that the net force on it is zero?
d = -1 m
The negative sign indicates that the charge from that force of the space of the two spheres.
What is charge ?When charged matter is exposed to an electromagnetic field, its electric charge—a property of matter—causes it to feel a force. An electric charge can be either positive or negative (commonly carried by protons and electrons respectively). Like and unlike charges are attracted to one another while being repelled by the other. Neutral describes a thing without any net charge. Classical electrodynamics, a term coined to describe early understanding of the interactions of charged particles, is still applicable to issues that do not demand for taking quantum effects into account.
The net charge, or the total of the positive and negative charges, is constant in an isolated system because electric charge is a conserved attribute. Electrical charge is transported by subatomic particles.

A. Acceleration during launch = 4000 m/s²
B. Distance that the froghopper moves while its legs are pushing = 0.002 m
Kinematics is sometimes regarded as a subfield of mathematics and is sometimes referred to as the geometry of motion. But in physics, it serves as the basis for classical mechanics. Without considering the forces that propel an item, kinematics studies how an object moves. It gives a description of the spatial positions of bodies or systems of material particles as well as the velocities and rates of change of those velocities.
t = 0.001 s
u = 4 m/s
PART A :
a = Δv / t
a = [tex]\frac{4m/s}{0.001s}[/tex]
a = 4000 m/s²
Therefore, Acceleration during launch = 4000 m/s²
PART B :
S = ut + [tex]\frac{1}{2}[/tex]at²
S = 0(0.001s) + [tex]\frac{1}{2}[/tex] x 4000 m/s² (0.001)²

a swimmer wishes to swim at a speed of 1.0m/s across river to a point A directly opposite him. There is uniform current with speed 0.5 metres per seconds. Find the direction in which the swim.er must head to do it
Answer:
The swimmer must swim at 1.12 m/s at 26.565 ° upstream from the opposing bank, according to the parallelogram rule of vectors.
What is parallelogram law of vector addition?
If two vectors act along two consecutive sides of a parallelogram (with magnitude equal to the length of the sides) both heading away from the common vertex, then the resultant is represented by the parallelogram's diagonal passing through the same common vertex.
Explanation:
Let, the current's speed be x = 0.5 m/s, the swimmer's speed be y m/s and the angle between them be a°. The resulting speed at b° angle with x will be r = 1.0 m/s. Assuming b is 90°.
Then, the parallelogram law of vectors states that
Sin b = y Sin a/r
=> y Sin a = r
=> y Sin a = 1
And Cos b = (x + y Cos a)/r
=> y Cos a = -x = -0.5
Therefore, tan a = 1/ (-0.2)
=> tan a = -2
As a result, a = 116.565°
Consequently, y = 1/Sin a
=> y = 1/ Sin116.565°
=> y = 1.118 ≈ 1.12 m/s

What is the speed of the electron?
Initial speed; v₀x = 1.1 * 10⁶ m/s
Acceleration in horizontal direction = 0 m/s²
distance; s_x = 2 cm = 0.02 m
Thus, formula to find time here is;

the home owner report that sometimes the electric furnace trip the 240-v 60-a circuit breaker connected to it
It is advisable to purchase a new circuit breaker with a higher capacity, perhaps a 240V, 80-100A circuit breaker, as breaker trips happen regularly.
We know that power is distributed as
P = IV
P stands for power in watts.
I is the same as current in amps.
And V stands for the voltage difference in potential.
The circuit breaker's function is to handle 240V, 60A.
A current of more over 60A will therefore trip the circuit breaker. The circuit breaker trips OFF when there is a significant amount of electricity flowing through it.
Three 5000W heating elements are now present in the furnace, and each of them trips the circuit breaker. Additionally, this element develops gradually; it does not happen all at once. When turned ON, the first component will draw the following amount of electricity from the mains:
We are aware that the initial heating element has a 3000W power rating.
P = IV
[tex]I' = \frac{P}{V} = \frac{3000}{240}[/tex]
I' = 20.833amps
The circuit breaker is still operational in this scenario because of its 60A capacity.
The second heating element eventually turns on.
Furthermore, this will result in a current of
[tex]I'' = \frac{P}{V} = \frac{3000}{240}[/tex]
I" = 20.833amps
the total current drawn at this time is I = I' + I" = 20.833 + 20.833
I = 41.667 amps
Once more, the 60A capacity of the circuit breaker makes it still appropriate.
Eventually, the third component will trip ON once more, drawing current from:
I"' = [tex]\frac{P}{V} = \frac{3000}{240}[/tex]
I"' = 20.833 amps
The current drawn overall is now I = I' + I" + I"'
I = 20.833+20.833+20.833
I = 62.5 Amps
The breaker will trip because the current exceeds the circuit rating.
Advice: Since replacing the furnace might be too expensive, I will suggest that they purchase a new circuit breaker with a higher capacity, possibly a 240V, 80-100A circuit breaker.
The complete question is : You have been sent to a new home. The homeowner reports that sometimes the electric furnace trips the 240-V, 60-A circuit breaker connected to it. Upon examination, you find that the furnace contains three 5000-W heating elements designed to turn on in stages. For example, when the thermostat calls for heat, the first 5000-W element turns on. After some period of time, the second element will turn on, and then, after another time delay, the third element will turn on.

Find the velocity of the car after 5.3 s if its acceleration is 1.1 m/s2 due north.
Initially, an automobile is moving north at a speed of 23 m/s. If the automobile accelerates at [tex]1.1 m/s^{2}[/tex] in the direction of travel, its speed after 5.3 seconds will be 28.83 m/s.
The initial speed of the car u = 23 m/s
Time is taken t = 5.3 s
Acceleration, a = [tex]1.1 m/s^{2}[/tex]
the first movement equation (Vf =Vi + at) offers with time, acceleration, very last pace, and starting pace. the first equation of motion can be used to calculate time, acceleration, beginning pace, and final pace.
Applying 1st equation of motion,
v = u + at
v = 23 + 1.1 × 5.3 (Since both beginning speed and acceleration are in the same direction)
⟹ v = 28.83 m/s (due North)

A crooked casino creates a 6-sided die with unequal probabilities. the probability of rolling a one is twice that of rolling any other number. a) what is the probability of rolling a 1?
The probability of rolling a one is twice that of rolling any other number.
Then the probability of rolling a 1 is 1/6.
What is probability ?The probability of something is how likely it is to happen. When we don't know how an event will turn out, we can talk about the probabilities of several outcomes—how likely they are. Examining events with a probability component is known as statistics.
Probability is a mathematical concept used to determine the likelihood of an event. It is challenging to make an accurate prediction for many events. We can only predict an event's likelihood, or how probable it is to occur, by using it.

Find the velocity and position vectors of a particle that has the given acceleration and the given initial velocity and position. a(t) = 3 i 4 j, v(0) = k, r(0) = i
The velocity vector is (v = 3ti + 4tj + k) and the position vector is (x = (3t²/2 + 1) i + 2t²j + tk)
We need to know about vector to solve this problem. The velocity is depend on position vector and acceleration. It can be written as
v = dx / dt
where v is velocity, dx is displacement and dt is time interval.
By differentiating the velocity function, we can also get the acceleration
a = dv / dt
where a is acceleration.
From the question above, we know that
a(t) = 3i + 4j
Hence, the velocity is
a = dv / dt
dv = a . dt
v = ∫a . dt
v = ∫(3i + 4j) . dt
v = (3i + 4j)t + v(0)
because v(0) is k, thus
v = 3ti + 4tj + k
Find the position vector
v = dx / dt
dx = v . dt
x = ∫v . dt
x = ∫(3ti + 4tj + k) . dt
x = (3t²/2 i + 2t²j + tk) + x(0)
because x(0) is i, thus
x = 3t²/2 i + 2t²j + tk + i
x = (3t²/2 + 1) i + 2t²j + tk
